Given a chemical equation, showing the dissociation of an acid in solution, be able to identify the "acid", the "base", the "con
Karo-lina-s [1.5K]

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory:

  • An acid is defined as a substance which looses donates protons and thus forming conjugate base
  • A base is defined as a substance which accepts protons and thus forming conjugate acid.

HA+H_2O\rightarrow A^-+H_3O^+

Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.

HA = Acid

H_2O = Base

A^- = Conjugate base

H_3O^+ = Conjugate acid

For example:

H_2SO_4+2H_2O\rightarrow SO_4^{2-}+2H_3O^+

Sulfuric acid dissociating in its solution to form conjugate base and conjugate acid.

Sulfuric acid  = Acid

H_2O = Base

SO_^{2-} = Conjugate base

H_3O^+ = Conjugate acid

C + 2H2 -&gt; CH4
ankoles [38]

Answer:

<u>C) 4</u>

Explanation:

<u>The reaction</u> :

  • C (s) + 2H₂ (g) ⇒ CH₄ (g)

       12g      4g             16g

Hence, based on this we can say that : <u>2 moles of hydrogen gas are needed to produce 16g of methane.</u>

<u />

<u>For 32g of methane</u>

  • Number of moles of H₂ = 32/16 × 2
  • Number of moles of H₂ = <u>4</u>
